I am getting my hands on a 465/205 hydro setup in the next week or so, and wanted to get out here and start asking everyone's experience converting from a TH400 to the 465. I am planning for a doubler setup later this year (possibly). But that is a whole other subject, I just want to make sure that I am not doing anything now (while installing the 465) that will make things more difficult when I go to do the doubler. Here is everything that I still need: 1. BBC flywheel 2. throw out bearing 3. pilot bearing 4. master cylinder & slave cylinder (for the hydro brakes) 5. flex line from master to slave 6. new driveshafts I know Ken and Layne both have hydro setups that use all the GM part numbers, and I have heard that the GM stuff makes a huge difference. Having said that I would like to hear what everyone has to say about the GM stuff vs. after market stuff. And anyone that has any of this stuff for sale, please let me know (just had to sneak that in here somewhere!) /forums/images/icons/smile.gif I'm looking for ALL the info I can get my hands on... if I get enough info, I will take the time to snap pictures throughout the R&R process, and create a writeup for this since it seems like quite a few people are doing this lately. Thanks folks!
